Definitions

  • the present invention relates generally to mobile communication systems, and more particularly to a method of paging a mobile unit in a mobile communication system.
  • mobile units In mobile or wireless communication systems, mobile units have the capability to roam within the wireless communication system.
  • the wireless communication system receives a call request for a mobile unit, the communication system has to locate the mobile unit in order to complete the call.
  • a mobile unit registers with the wireless communication system when powering up, and also when placing a call. It would be desirable to have the communication system know the location of all mobile units at all times, but this would require each mobile unit to send a location update each time it moved into a new cell. This would be extremely inefficient, since the communication system only need to know the location of the mobile unit when an incoming call request is received, and also because the number of update messages would consume bandwidth that is needed by the communication system to handle calls within the communication system.
  • the process of paging a mobile consumes many resources within the MSC. These resources include bandwidth over the paging channel, processor occupancy of internal network elements, and the bandwidth for signaling messages between those elements. Paging is costly because the page is generally broadcast to many cells which might contain the mobile unit. If too few cells receive the page, one risks missing the mobile unit. If too many cells receive each page, resource shortages may ensue.
  • an MSC Mobile Switching Center
  • Paging algorithms typically start by broadcasting to a narrow group of cells, and then broadcast to progressively larger groups in hope of eventually finding the mobile unit. Ideally, one would start with a very small number of cells, perhaps just a single cell, and then progressively widen the scope.
  • delivering a call to a mobile unit is time-critical. The calling party is likely to abandon the call before the mobile unit is found if too many paging attempts are necessary.
  • the present invention provides a method for determining a mobility index for a mobile unit in a wireless communication system.
  • the mobility index is used to determine an efficient paging strategy for locating a mobile unit.
  • a mobile unit is not mobile, but stationary.
  • a typical subscriber of a mobile unit is mobile during certain times of the day, such as when driving to and from work, but is stationary during other times of the day, such as when at work or at home.
  • the present invention utilizes a method for determining the best method of paging a mobile unit, based on the likelihood that the mobile unit is in a particular cell or other interaction area.
  • the present invention provides a method for paging a mobile unit by an MSC.
  • the MSC calculates the probability that a mobile unit is in the same cell or group of cells as when it last interacted with the MSC based on a mobility index associated with that interaction and the elapsed time since that interaction.
  • the MSC can therefore avoid wasting time on paging strategies with a low probability of success.
  • the mobility index is preferably calculated based on the last interaction of the mobile unit with the MSC.
  • the mobility indices are preferably calculated for every sector of every cell, and also for the MSC as a whole.
  • the mobility indices can also be calculated for any well-defined interaction area.
  • the MSC can calculate the mobility index for being within the same cell and its immediate neighbors, for being within the same sub-MSC paging area, or for being within the same MSC. In further exemplary embodiments, the MSC can calculate the mobility index for different times of day and for different subscribers.
  • the MSC determines the last interaction of the mobile unit with the MSC.
  • the MSC determines the cell and sector of the mobile unit for the last interaction.
  • the mobility index is a function of the cell sector.
  • a cell sector serving a busy highway implies high mobility, while a cell sector serving a shopping mall, for example, implies low mobility.
  • the MSC determines the time of the last interaction.
  • a location-based registration which occurs when a mobile unit moves into a new paging area implies high mobility.
  • a time-based registration, periodically generated by the mobile unit, implies low mobility. All aspects of the interaction: cell, sector, interaction type, time of day, and the class of mobile unit can be used to calculate a mobility index.
  • the exemplary embodiment of the present invention uses cell, sector, and interaction type for calculation.
  • the MSC After determining the mobility index, the MSC then determines the paging strategy.
  • the paging strategy is preferably determined based upon the probability of paging success, which is a function of the mobility index and the elapsed time since the last interaction.
  • the present invention allows an MSC to determine its first paging strategy based on the mobility implied by the last interaction the mobile unit had with the MSC and how long ago the interaction occurred.
  • the present invention thereby allows an MSC to use a single cell page and/or neighbor page on a mobile unit expected to be stationary. Considerable paging load is thereby reduced in the wireless communication system.
  • the present invention provides a methodology for wireless services to locate mobile units through an efficient paging strategy based on each mobile unit's mobility index, thereby providing for the delivery of calls with minimal yet effective paging resource consumption.

  • Base stations 111 through 117 communication with mobile units located within their cells.
  • Mobile units can move from cell to cell, in which case communication with the mobile unit is handed off to the new base station that is associated with the new cell.
  • a typical mobile unit spends a minority of its time in motion, such as when commuting to and from work, and a majority of its time stationary, such as at home or when in the office.
  • a cell page to cell 117 pages all sectors of cell 117 and nothing else.
